How much more can I OC with my PCI bus at 37MHz?

[Garfield]

I'm currently OCing my system (see sig) and right now my FSB is 147 and my divider is 1/4x (can't go any higher). That makes my PCI bus speed to be 37MHz. How much further can I go for everything to remain stable? Does anybody have any experience with the hardware that I'm OCing to know when everything is still stable (HDD, Video card, sound card, other ports)?

Right now I have a 42 PCI Bus, everything is different, but usually HDD can take it up to 40 at least.

Although WD drives seem to be bad at taking those high speeds. What's it giving you file corruption errors?

Well, if the hdd was an issue, than that wouldn't stop you from booting, just you'd get corrupt data over time...

That leaves that RAM, video card, and soundcard. Since you need RAM and video, try pulling the soundcard out and seeing if you can get anymore fsb...

Also, as you up the FSB, it should chance divisors...so, for kicks, raise the fsb until the 1/5 divisor kicks in, which if you're at 37mhz should be pretty soon.

Most pci stuff I've dealt with has worked reasonably well at 37...not all of it ofcourse, but I had a SiS 6326 agp card running with the pci at 39mhz...and those SiS video cards are strictly for light 2d business apps.

Just try and work though the variables you have...try to get to the 1/5 divisor, and take stuff off the pci bus that you don't need.

If you have NIC, pull it...those are usually the first items to cause a problem.


Goodluck!

No, I haven't had any problems with anything (to my knowledge) yet, I'm just not sure what to bring it up to. I always thought going more than 38 was pushing it, but by what you guys say, it's not really.

I can't get a 1/5 divisor. My 8KHA+ only goes up to 1/4 and I would have to get a BIOS update to do that.

Seems to be that my hard drive will keep me back in the future. I hope I don't have any corrupted data when I raise the FSB more. Would you have to reformat the hard drive then and install everything again? That would be terrible...

thought id post this here

someone told me that the 1/5 kicks in at 150 FSB
and then like 1/6 at 166 which would set me bacl
to normal.

i cant get any FSB at all cuz of my old cheapo hard drive.
i get really bad BSOD and file corruption on any FSB icrease.
so bad that i have to reinstall windows XP.

so if i jumped to 166, i wouldnt get a higher PCI frequency
which means my HDD would run at default which means OVERCLOC?

i think i can cool it, i have a Glaciator II and ASII. my xp
1600 run sat 42C after 3 days & nights straight of continous FOLDING!!!

any feedback would be great. thanks

DARN!

tried to boot at 166 @ a 1.80 v-core
no post, just black screen (that is no post, right???)

so, no overclocking for poor ol me unless i unlock this thing.

To my knowledge the only mobo with a 1/5 and 1/6 pll divider is the gigabyte GA-6OXET(-C)
